HRM 3440 Lecture 34 Notes – Data Analysis, Identifying Sources of Data and Collecting Data
Introduction
Identifying Sources of Data
• Data collection begins by identifying and locating the various sources of data, including
both internal and external sources.
Collecting Data
• After data sources have been identified, data collection begins.
• The steps involved.
• Data collection might require a number of tools and techniques, such as interviews,
direct observation, and questionnaires.
• Interviews can either be structured or unstructured.
• In a structured interview, the questions are written in advance.
• In an unstructured interview, the questions are not written in advance
• The interviewer relies on experience in asking the best questions to uncover the
inherent problems of the existing system.
• With direct observation, one or more members of the analysis team directly observe the
existing system in action.
• When many data sources are spread over a wide geographic area, questionnaires might
be the best method.
• Like interviews, questionnaires can be either structured or unstructured.
• In most cases, a pilot study is conducted to fine-tune the questionnaire.
• A follow-up questionnaire can also capture the opinions of those who do not respond to
the original questionnaire.
Data Analysis
• The data collected in its raw form is usually not adequate to determine the effectiveness
of the existing system or the requirements for the new system.
